JEFFERSON ARTHUR GARFIELD HARTON, OF NEW YORK, N. Y.

GUIDE-PLATE FOR CORRECTION-TYPE.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed May 7. 1907 Serial No. 372.450.

T 0 all whom it may concern:

Be it known that I, JEFFERSON ARTHUR GARFIELD HARTON, a citizen of theUnited States, residing in New York, in the borough of Brooklyn, countyof Kings, and State of New York, have invented certain new and usefulImprovements in Guide-Plates for CorrectionType, of which the followingis a specification.

This invention relates to an improved guide-plate for the correctiontypeused in correcting type or words in type-written documents; and for thispurpose the invention consists of a guide-plate for the correctiontype,which consists of a plate of celluloid or other suitable materialprovided with a longitudinal slot, said longitudinal slot having anopening transversely of said slot for guiding the shank of thecorrection-type.

The invention consists further of a rectangular plate of celluloid orother suitable material which is provided with ways and a shiitableplate in the same and provided with a heel used as a handle, alongitudinal slot, and a rectangular opening transversely to the same,as willbe fully described hereinafter and finally pointed out in theclaims.

In the accompanying drawings, Figure 1 represents a perspective view ofmy improved guide-plate for the correction-type for typewritings, Fig. 2is a vertical trans verse section showing the use of the plate inconnection with a correction-type, Fig. 3 is a perspective view of amodified construction in which the guide-plate is shiitable in asuitable guide-frame, Fig. 4 is a transverse section on line 4, 4, Fig.8, and Fig. 5 is a longitudinal section on line 5, 5, Fig. 3.

Similar letters of reference indicate corresponding parts throughout theseveral figures.

Referring to the drawings, a represents a guide-plate for thecorrection-type which is used in correcting typewritten documents eitherby inserting a letter or character or words in the same withoutreplacing the doc uments in the typewriting machine. The guide-plate ais made of celluloid or other suitable material and provided with alongitudinal slot 1) which serves for locating the position of the typeor word to be corrected.

The longitudinal slot is provided with a transverse slot b ofrectangular shape, which corresponds in size to the shank of the type,so that when the type is placed in the same it is guided exactly to thepoint where the type is to be printed. By cutting the transverse slot bintermediately of the length of the longitudinal slot, it is possible tosee through the latter slot at both sides of the former and therebydetermine the point where the letter should be placed. The shanks of thecorrection-type are made of the same size and cor respond to thetransverse opening in the guide-plate a.

When more than one type is to be corrected, or a word is to be insertedin a typewritten document, the guide-plate a is supported in a fiatoblong guide-frame d which is provided with a longitudinal guide-s1othaving grooved edges d in which. the guide-plate is guided, as shown inFigs. 4 and 5. Thus both the guide-frame and the guide-plate lie in thesame plane. In this case the guideplate is provided w ith a heel h whichserves as a handle for moving the guide-plate in the guide-frame. Thispermits the quick insertion of several type at the required location.

The advantage of my improved guide-plate for correction-type for type-writings are that corrections can be easily made at the requiredlocation without separating the sheets of documents from each other andreplacing them in the typewriter; that an outfit of correction-type andguide-plates forms a convenient accessory for typewriting machines; andthat an outfit can be furnished at a comparatively low price and saves agreat deal of time in correcting typewrittendocuments, and especiallysuch which are tied up and cannot be separated into individual sheets.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent:

1. The combination, with a guide-frame having a longitudinal slot withgrooved edges, of a guide-plate having its edges movable in the groovesof said slot said guideplate being provided with a longitudinal slot,

and a type-guiding opening cut in said slot intermediately of the lengthof the latter.

2. The combination, with a guide-frame having a longitudinal slot withgrooved edges, of a guide-plate having its edges movable in the groovesof said. slot, said guidemy invention, 1 have signed my name in platebeing pro ided With a, longitudinlal slot presence of two subscribingwitnesses. ant a t e 'u1 in 0 ening iI1tQI111G(iLt6 1 x Y of the l iitfiof sail l stmzimed slot, and JhFFERbOh ARTHUR GARFIELD HARTON' 5 handlefor the guide-plate by which it is Htnesses:

In testimony, that I claim the foregoing as HENRY J. SUTIRBIERQ
